note 73889 added to ref.mbstring

Note that some of the multi-byte functions run in O(n) time, rather than constant time as is the case for their single-byte equivalents. This includes any functionality requiring access at a specific index, since random access is not possible in a string whose number of bytes will not necessarily match the number of characters. Affected functions include: mb_substr(), mb_strstr(), mb_strcut(), mb_strpos(), etc. ---- Server IP: 69.147.83.197 Probable Submitter: 128.208.1.163 ---- Manual Page -- http://www.php.net/manual/en/ref.mbstring.php Edit -- https://master.php.net/note/edit/73889 Del: integrated -- https://master.php.net/note/delete/73889/integrated Del: useless -- https://master.php.net/note/delete/73889/useless Del: bad code -- https://master.php.net/note/delete/73889/bad+code Del: spam -- https://master.php.net/note/delete/73889/spam Del: non-english -- https://master.php.net/note/delete/73889/non-english Del: in docs -- https://master.php.net/note/delete/73889/in+docs Del: other reasons-- https://master.php.net/note/delete/73889 Reject -- https://master.php.net/note/reject/73889 Search -- https://master.php.net/manage/user-notes.php
